--- Comment #1 from Iain Buclaw <ibuclaw@gdcproject.org> ---
Likewise, this fails to compile:
---
enum constant_expression
{
  ce_first,
  ce_second = (int) ((1UL << (ce_first)) << 24),
};

This is the full example from `wctype.h`.

---
enum
{
  __ISwupper = 0,
  _ISwupper = ((__ISwupper) < 8
    ? (int) ((1UL << (__ISwupper)) << 24)
    : ((__ISwupper) < 16
        ? (int) ((1UL << (__ISwupper)) << 8)
        : ((__ISwupper) < 24
            ? (int) ((1UL << (__ISwupper)) >> 8)
            : (int) ((1UL << (__ISwupper)) >> 24)))),
};
